The Hilo Tsunami
The Hilo Tsunami: In an M 9.5 earthquake, the largest recorded in the 20th century, pressure between 2 major convergent plates finally gave way, vibrating all the way to the Earth's core. Several shocks caused the land to sink as much as 7 feet and rise as much as 13 feet in different places.
A destructive Tsunami spread up the coast and across the Pacific Ocean at speeds up to 442 miles per hour. The tsunami reached Hawaii in 15 hours killing 61 people and 8 hours later struck the Japanese coast, killing 185 more. A volcano in Chile also became active and erupted.
